STEP-BY-STEP SOLUTION:
= a^3 - 4a^2 + 12 - 3a
= a^2 ( a - 4 ) + 3 ( 4 - a )
= a^2 ( a - 4 ) - 3 ( a - 4 )
= ( a - 4 ) ( a^2 - 3 )

Answer:
21.5
Step-by-step explanation:
Let 5w equal the length and w equal the width.

ANSWER: 11.08
EXPLANATION: Add a zero after the 9 to make the number 29.90. Then subtract normally.
1)√3 = 1.73 (near +2 left)
2)√10 = 3+something (near +3, towards RHS)
3)√26 = 5+something (near +5, towards RHS)
4)-√5 = -2-something (near -2 towards left)
5)-√14 = -4+something (near -4 towards right)
